PyChart is a <a href="http://www.python.org">Python</a> library for
creating high quality Encapsulated Postscript, PDF, PNG, or SVG charts.  It
currently supports line plots, bar plots, range-fill plots, and pie
charts.  Because it is based on Python, you can make full use of
Python's scripting power. See some <a
href="examples/index.html">examples</a>. 

<p>I've used PyChart to draw some real graphs to publish some real
papers (see my <a href="../sosp.ps">SOSP</a> and <a
href="../tocs.ps">TOCS</a> papers for example).  So it's for real!

Here are links to some competitors, in case you don't like PyChart:

<ul>
<li><a href="http://www.linmpi.mpg.de/dislin/">Dislin</a>.<br>
Dislin does 3-D plots, but it's not as configurable or as pretty as pychart.
<li><a href="http://www.sgpr.net/">Ploticus</a>.<br>
Ploticus inspired PyChart most. It can produce a very pretty output, but
writing a script for Ploticus is incredibly cumbersome.
<li><a href="http://www.gnuplot.org/">Gnuplot</a>.<br>
A long-time favorite of researchers. But its output is not up to 
publishing standard, in my opinion.
